Heterogeneous Catalysts for Biodiesel Synthesis By Transesterification

摘要

This review focuses on the heterogeneous base-catalyzed Trans esterification in terms of catalyst development, based on the published research, especially over the last decade. Heterogeneous base catalysis is the most viable process for the Trans esterification of triglyceride into biodiesel. The research and development on heterogeneous base catalysis for biodiesel synthesis have focused mainly on improving its slow reaction rate up to the level of its homogeneous counterpart. The heterogeneous catalysis features lower corrosiveness, environmental friendliness, easy catalyst recovery and high process integrity, all at levels superior to those of homogeneous catalysis.
